Abstract

Patients with unilateral frontal or temporal excisions and normal control subjects were required (1) to copy single, difficult positions of the arm, fingers, or both, and (2) to copy the experimenter as three hand positions were presented one after the other at an increasing rate. All patient groups were impaired relative to the control group on both tasks, but on the second task patients with frontal lesions were also impaired relative to those with temporal lesions. Results suggested a role of the left- and right-frontal lobes in rapid execution of multiple manual responses.

      They ascribed these results to deficits in short-term memory and in the programming of movements. Moreover, patients with frontal lobe lesions show difficulties in the rapid production of a series of manual responses (Jason, 1986), in a bimanual tapping task (Leonard et al., 1988) and in the attentional control of unpractised movements (Richer et al., 1999). The role of the frontal lobe in motor planning is further supported by the observation of the frontopolar maximum of a cortical direct current (DC) shift (motor intention potential, MIP) related to the conscious intention of a voluntary movement (Keidel, 1983).
